◆ Binlog_file_reader

Binlog_read_error::Error_type binlog_event_deserialize	(	const unsigned char *	event_data,
		unsigned int	event_data_len,
		const mysql::binlog::event::Format_description_event *	fde,
		bool	verify_checksum,
		Log_event **	event
	)

Deserialize a binlog event from event_data.

event_data is serialized event object. It is a chunk of data in buffer.

Parameters

[in]	event_data	The event data used for deserialization.
[in]	event_data_len	Length of event_data
[in]	fde	The format_description_event of the event
[in]	verify_checksum	Verify event_data's checksum if it is true.
[out]	event	the event object generated.

Return values

Binlog_read_error::SUCCESS	Success
Other	than Binlog_read_error::SUCCESS Error
